IMPROVEMENT IN GLASS PANELS.

Specification forming part of Letters Patent No. 178,904, dated J line20, 1876; application filed April 1,1876.

To all whom it may concern Be it known that I, JAMES BUDD, of the city,county, and State of New York, have invented certain new and usefulImprovements in Panels for Railroad-Cars, of which the following is aspecification:

This invention relates to the construction of the exterior panels ofrailroadcars, and it is particularly designed for that class known aspalace, parlor, and sleeping cars. It consists in dispensing with theusual varnished hard-wood panels, and substituting therefor glass panelssuitably ornamented on the interior surface, in the manner as will behereinafter fully pointed out and claimed.

In the drawings, Figure 1 represents a side elevation of an ordinarypassenger car in which is fully embodied my invention and Fig. 2represents an enlarged cross-section of a glass car-panel, showing theapplication of the ornamenting material.

The present method of finishing the exterior panels of the expensiveclasses of railroadcars known as palace, parlor, and sleep;

ing cars, by means of hard-wood panels which are highly polished andvarnished, has many difficulties, the obviating of which is a greatdesideratum. It is desirable to A have them always present a new andbright appearance, and in the process of cleaning the exterior coatingof varnish is quickly dulled and worn off, exposing the wood, whichquickly deteriorates by the action of the elements, thus necessitatingthe frequent withdrawal of the car from duty for the purpose ofrevarnishin g and repairs.

In carrying out my invention I dispense with the exterior wood panelingof the car, and insert in the frames or moldings glass panels, which areornamented on their rear surface with such stripes, figures, designs, orimitations of wood as may be desired.

In the process of ornamentation, the panel of glass is first thoroughlycleaned. It is then coated with white shellac varnish, which is flowedon the-surface, so as to insure an even coating. When dry, theornamental stripes or colored figures or designs are painted upon theshellaced surface in oil-colors, as fancy or taste may call for. Thesestripes and figures, when dry, are then covered with shellac the glasswith a brush, in the ordinary man-" When dry, this final coat of coloris V ner. entirely covered with a coating of thick shellac varnish, thealcohol being evaporated therefrom, so as to leave it in a thick pastycondition, which is immediately coated with plaster-of-paris. This maybeapplied or sifted on by any means desired, so that it is evenlydeposited. The shellac at once absorbs the 'plaster-ofparis, thecombination of the two drying quickly and forming an impervious coating.

In Fig. 2 of the drawings the applications of these various coatings tothe glass are shown, thesame being drawn on an enlarged scale, for thepurpose of plainly indicating each stage of the process and application.A

represents the glass; B, the first coating of 1 shellac varnish; a, theornamental striping figures, or designs; b, the coating of shellacvarnish applied over them for the purpose of making their rear surfaceidentical with the previously-coated surface of the glass. D representsthe final or body coating of plain color, and F the final or finishingcoating of impervious matter.

The object of first coating the glass with shellac varnish is to providea suitable base upon which to lay the oil-colors, which shall preventthe paint from blistering or peeling off by the action of the sun, orfrom other exposure, which would occur were the oil-colors laid directlyupon the glass surface. The stripes and ornamental designs inoil-colors, after being laid, are also covered with shellac, so as tomake the entire surface alike for the application of the final coat ofcoloring. The

finishing coating of shellac and plaster-ofparis is for the purpose ofpreventing any dampness from reaching the colors in case any watershould get in between the glass panel and the wood backing forming theinterior of the car. v

I make no changes in the general construction of the car, merelyomitting the exterior wood panels.

The glass panels'may be set into a bed of any elastic material attachedto the moldings which will give tight but elastic joints, and

also provide for any variations caused by ex pansion and contraction.

It is plainly apparent that a car provided with these glass panels,ornamented as deapplying the design thereon in oil -colors third, againcoating the whole with shellac; fourth, applying a'coat of coloring,and, finally, backing the whole with thick shellac val"- nish andplaster-of-paris, substantially as and for the purposes set forth,

shellac varnish, a design in oil-color, asecond coat of shellac, acoatof coloring, and a backing of thick shellac varnishpand plaster-ofparis,substantially as and for the purposes set forth. 7
